HAMMOCK-SWINGING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 483,753, dated October4, 1892.

Application tiled October 9, 1891. Serial No. 408,213. (No model.)

To @ZZ whom. t may concern:

Beit known that I, CHRISTIAN WASHBURN, a cltizen of the United States,residing at Brldgewater, in the county of Plymouth and State ofMassachusetts, have invented certain new and useful Improvements inHammock- Swinging Apparatus, of which the following, taken 1n connectionwith the accompanying drawings, is a specification.

The object of my invention is to produce a haminock-swin ging apparatuswhereby a person 1n the hammock can cause it to swing by a slight motionof the hand.

'The invention consists of a bell-crank lever pivoted to an arm that issecured to one of the posts or supports carrying the hammock, and a cordconnecting the short arm of the lever and the rope of the hammock, andanother cord attached to the long arm of the lever, which cord isoperated by the person occupying the hammock.

Referring to the accompanying drawings, Flgure l represents a hammocksupported from two posts, to one of which is attached a swlnglngapparatus embodying my invention. Fig. 2 is a plan or top view of oneend of the same, drawn to a larger scale. Fig. Sis an lsometricalperspective View of the swinging apparatus.

A A represent posts provided with hooks B B, to which the hammock C ishung.

D 1s an arm secured to one ot' the posts A a short distance below thehook B. To the outer end of the arm D is pivoted a bellcrank lever E, tothe short arm e of which is secured one end of a rope F, the other endof which is looped and passed over the hammock-rope C before it isplaced upon the hook B. To the long arm e of the bellcrank leverE issecured a long rope G, the free end of which extends toward and rests inthe hammock, so as to be operated by the occupant.

In the drawings I have shown rings secured to the end of each arm ofthebell-crank lever for attaching the ropes; but of course they could beformed with holes and the rings be dispensed with.

As the hammock is suspended longitudinally between the supports, one ateach end, its movement is in the nature of a partial rotation with thepoints of suspension, as an axis, and as the main portion of it when atrest is suspended from the supports the bellcrank lever must be pivotedso that its arms will move in a horizontal plane, so that when the drawupon the `longer cord is exerted the motion will be transmitted to thehammock to move it in a lateral direction, and as the movement orswinging of the hammock is increased the suspended portion will move inthe arc of a circle. The construction of applicants device also admitsof the hammock being operated in narrow halls or on verandas, where itis necessary to have the operating mechanism as compact as possible toavoid being in the way, and also to avoid all undue friction as wherethe cord would be passed over a pulley and also to permit of this forcebeing exerted by the short movement of the arm that can be had when aperson is lying in a hammock.

The operation is as follows: The person oc cupying the hammock takeshold of the rope G and draws upon the same, which communicates motion tothe bell-crank lever E, and by the rope F to the hammock-rope C,Vandcauses it to vibrate and thus impart aswinging motion to the hammock. Itwill be seen that a very slight movement imparted to the cord C' willcause the hammock to swing a considerable distance, thus the operatorhas to move his hand but slightly and that in a` line longitudinally ofhis body if he is lying down.

What I claim as my invention ism- The combination, with two supports, ofa hammock horizontally suspended therefrom, the connection between thehammock and the supports being such that the hammock can have a lateraland vertical movement relatively to the supports, a bracket secured toone of the supports and projecting laterally therefrom relatively to thehammock, a bellcrank lever pivotally secured at its angle to the outerend of the bracket, with its arms movable in a horizontal plane, one armof the lever projecting toward the center of the hammock and the otherarm projecting substantially toward the support, a cord secured to theouter end of the first-mentioned arm and connecting with the hammocknear the support, and another cord secured to the outer end IOO of theother a-rrn and extending to the central two subscribing witnesses,ronthis 7 th day of portion of the hammock and adapted.- to be August, A.D. 1891. drawn longitudinally by the occupant, said cords crossing eachother near the support, 5 substantially as set forth. Witnesses:

In testimony whereof I have signed my JOSEPH TOOKER, name to thisspecification, in the presence of LORIN HEITH.
